Euripides was a tragedian of classical Athens. He is one of the few whose plays have survived, with the others being Aeschylus, Sophocles, and potentially Euphoric. Some ancient scholars attributed 95 plays to him but according to the Sudan it was 92 at most. Of these, 18 or 19 have survived more or less complete (there has been debate about his authorship of Rhesus, largely on stylistic grounds) and there are also fragments, some substantial, of most of the other plays. More of his plays have survived intact than those of Aeschylus and Sophocles together, partly due to mere chance and partly because his popularity grew as theirs declined he became, in the Hellenistic Age, a cornerstone of ancient literary education, along with Homer,Demosthenes and Menander.
